First, let me say thanks for all the accolades but credit must be given to my new camera. Had been using a 4 MP model, now I'm using a 8 MP Fuji FinePix S8000fd.
Now to your questions ... Nothing special about the ribs, all were on special (I'm cheap) some sides, some BBs. I only removed the membranes ... very little fat needed to be trimmed. Marinated them overnight in low-acid aple juice. Used Jeff's rub mixed with a commercial rub and finished with BBQ sauce. Smoked for 3½ hrs, spritzing with apple j ... did not foil ... basted with BBQ sauce for 3 more hrs.
Had a little too much tug (didn't come clean off the bone) for my taste, but were very moist and tender.
